Hello, thanks to those who responded to my question of whether to do MRI or ultrasound post bilateral mastectomy as a screening tool. My follow up question is for those who has a MRI following mastectomy. How likely is it for false positives to occur when there is scarred and inflamed tissue resulting from the surgery. It has been a year since my preventive double mastectomy without reconstruction for LCIS. I want to pay for a MRI because while my doctors do not think I need it, I will feel better knowing rather than assuming that everything has been removed. But the other part of me is nervous about having to deal with the possibility of having to go through more testing, especially since MRIs are known for its high rate of false positives.
